Quantity audio can either make or break your film.
Built in microphones are not very good so using a shotgun microphone will improve your sound.
Shot gun mics pickup all the sound behind you so try to avoid tiles and walls ’cause they can rebound the sound.
Always use headphones.
If you’re using HFD take off the cap, slot it in and turn it clockwise and then get a teacher to check it.
Our task was to record just with the inbuilt cam; poor audio and with the shotgun mic plugged in but turned off and then record with shotgun mic turned on and plugged in; this resulted in the best sound.
